I'd put a good amount of weight the behind the cab in your truck to help control the trailer. The trailer probably outweighs the half ton truck and that's not a good combination on slick roads. You need to watch out on sharper corners. The trailer's momentum is going straight ahead as the truck turns into the corner. This can jackknife the truck pushing it off the outside edge of the corner. When the trailer weighs more than the truck, if you let off the gas, the trailers momentum will control the situation. So slow down before the corner, not in the corner.
